每當我要將文件寫入文件夾時，我都會遇到此錯誤。訪問路徑'xxxxxxxxx'被拒絕
這裏是我的代碼：發生
protected void ListAttachments(List<MessagePart> msgParts)
{
bool attachmentsFound = false;
StringBuilder b = new StringBuilder();
b.Append("<ol>");
foreach (MessagePart p in msgParts)
{
string contentType = p.Headers["Content-Type"];
string contentDisposition = p.Headers["Content-Disposition"];
Match m;
if (contentDisposition != null)
{
m = FilenameRegex.Match(contentDisposition);
if (m.Success)
{
attachmentsFound = true;
b.Append("<li><a href='Handler.ashx?fileName=" + m.Groups["filename"].Value + "'>").Append(m.Groups["filename"].Value).Append("</a></li>");
Response.AppendHeader("content-disposition", "attachment; filename=" + m.Groups["filename"].Value);
Response.ContentType = "application/octet-stream";
//Error Occurs
Response.TransmitFile(Server.MapPath(@"~/Files"));
Response.End();
}
}
else if (contentType != null)
{
m = NameRegex.Match(contentType);
if (m.Success)
{
attachmentsFound = true;
b.Append("<li><a href='Handler.ashx?fileName="+m.Groups["filename"].Value+"'>").Append(m.Groups["filename"].Value).Append("</a></li>");
}
}
}
b.Append("</ol>");
if (attachmentsFound)
AttachmentsLiteral.Text = b.ToString();
else
AttachementsRow.Visible = false;
}
以下錯誤，如Access to the path 'F:\Gmail\Files' is denied。
這是錯誤的詳細信息：
Server Error in '/Gmail' Application.
Access to the path 'F:\Gmail\Files' is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access to the path 'F:\Gmail\Files' is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
